Strap on your wakizashi and stock up on shuriken: For the next four days, the screens at Anthology Film Archives will be dominated by the elusive masters of ninjutsu, thanks to Old-School Kung-Fu Fest 2015: Enter the Ninja. The films range from serious Sixties thrillers (Shinobi no Mono Parts 1 and 2, Sunday at 5:15 and 7:30) to the gung-ho cheese-fu of 1985’s American Ninja, Saturday at 3. (And for sheer crazytown fun, stick around for Five Element Ninjas. Ninja stilts, everybody. Ninja trees!) Friday’s 7:20 screening of a rare 1970s gem is shrouded in secrecy, as the ninja code demands. Showtimes vary.
